Target entity: Fleming’s right-hand rule Context triple: [John Ambrose Fleming, knownFor, Fleming’s right-hand rule]
-
A.
Fleming’s left-hand rule
Fleming’s left-hand rule is a mnemonic used in electromagnetism to predict the direction of force on a current-carrying conductor in a magnetic field.
-
B.
Lenz's law
Lenz's law is a fundamental principle of electromagnetism stating that an induced current or electromotive force always acts in a direction that opposes the change in magnetic flux that produced it.
-
C.
Faraday's law of induction
Faraday's law of induction is a fundamental principle of electromagnetism that relates changing magnetic flux through a circuit to the induced electromotive force (voltage) in that circuit.
-
D.
Ampère's force law
Ampère's force law is a fundamental principle in electromagnetism that quantifies the mechanical force between electric currents in conductors.
-
E.
Ampère–Maxwell law
The Ampère–Maxwell law is one of Maxwell’s equations that relates magnetic fields to electric currents and changing electric fields, thereby introducing the concept of displacement current and enabling the prediction of electromagnetic waves.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
